Producing animal protein is one of the most energy intensive forms of agriculture on the planet; farming animals is responsible for 12% of global Greenhouse Gas emissions. This figure is likely to rise in the coming decades as more and more people around the world are consuming a diet rich in meat, dairy, and eggs.

Over the past 50 years, farming animals has resulted in massive land use changes. While advances in agricultural science and animal genetics may have marginally increased the efficiency of the “supply-side,” many people—including animal advocates—recognize that “demand-side measures” need to be included to meet climate targets.
